PS Sorry I should have included the Lunar distance method as capitalised below ............It looks as if Cook might have used a process such as recalibrating his clock for local time every day against sunrise, sunset and noon. The clock would then only have to remain within spec for 24 hours AND MEASURE LOCAL TIME and not for months or years to maintain synchronism with Greenwich. Presumably there were enough stars visible in both the southern and northern hemispheres so that Cook in Australia could use the tables developed at Greenwich TO TRY OUT THE LUNAR METHOD...........
